He's not playing many minutes, but he's playing hard. I think the manimal's attitude has rubbed off on him.
Also Olajuwan's coaching has made him smoother and more confident on offense. I suspect he will continue to improve on defense.
Is this a coincidence? I don't think so. The writing was on the wall that he would improve after getting out of DC.
This situation says more about the ownership/management of the Wizards than about McGee.
Is Wall next to blossom elsewhere?
